BBC's Doctor Who is set to air an all-new Season 7 episode this Saturday, which is titled, The Name of the Doctor.

The respective installment will reportedly "serve as a seismic shift for the series forever," according to Carter Matt.

The site goes on to report that the Doctor (Matt Smith) and Clara (Jenna Louise-Coleman) will both continue to change and develop as characters, with the next episode revealing a few shocking things about each of them.

Executive producer of the series Steven Moffat recently spoke to the site about this Saturday's show, and is even stating that it will be one for the series' history books.

"[It will] change the course of Who forever ... It's full of surprises and questions that have never been answered in the history of Who, including the Doctor's greatest secret," he explained.

Smith also chimed in on his character's latest story arc, and how it will ultimately tie into the current season.

"I think throughout this season, we're building up to the revelation in the last episode - and then it kicks us on somewhere else."

Doctor Who will next air on Saturday, May 18 in the U.K on the BBC network.  Keep checking back for more of the latest details on the popular British drama.
